PETER BILHORN, OF CHICAGO, ILLINOIS.

PORTABLE ORGAN.

SPECIFICATION forming part of Letters Patent No. 439,625, dated November 4, 1890.

Application filed April 5, 1890 Serial No. 346,764. (No model.)

To all whom it may concern.-

Be it known that I, PETER BILHOBN, of Chicago, in the State of Illinois, have invented certain new and useful Improvements in Portable Organs, of which the following is a specification.

My invention relates to portable organs, and the object of myiinprovements is to make the box light and certain other of the details capable of being conveniently folded, whereby the instrument is made capable of being easily carried about and set up for use. This object I have attained in the instrument constructed as illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the organ as it appears when open and set up for use. Fig. 2 is a like view of the same closed and folded. Fig. 3 shows in elevation a view of the bottom or under side folded. Fig. & is an enlarged transverse vertical section. Fig. 5 is an enlarged longitudinal sect-ion on the line 5 5 of Fig. i, looking toward the right. Fig. 6 is a front elevation with a portion of the front board broken away.

The boX is composed of a frame embracing corner-posts 1, which are connected by longitudinal pieces 2, 3, 4t, 5, and 6, the bottom board 7, the middle board 8, and crosspieces 9 and 10, all firmly and substantially secured together. The corner-posts and cross-pieces 4 and 9 are provided with grooves, as shown at 11, which are adapted to receive the ends and edges of thin boards made of three-ply veneer, which may be slid into the grooves of the frame to form the exterior of the box. At the rear there is also a board 13, which extends between and is secured to the rear corner-posts, and inside of this there is a board 14, placed inward sufficiently to form passage 16 for admitting the air through the openings 17 and down through the ways at 18 into the feeding-bellows 19, the lower or movable portions of which are pivoted at 20 to the rear of the frame. The wind-chest, composed of the bottom board 21 and the flexible side and end pieces 22, is placed immediately above the feeding-bellows, and the air may be exhausted therefrom through the openings 17 and passed through valves 23 in such manner as to raise the bottom and compress the windchest, and thus by suction cause the wind to pass through the reeds when the keys 25 are operated, so as to open the valves by pressure on the pins 27in the usual way. The keys are guided on pegs 28, and the reed-valves are similarly guided on pegs 29, secured in the top board 8 and held normally closed by springs 30.

The swell 31 is hinged to piece on the reed cap or cover 32, and is operated by a crankrod 33, the rear crank of which engages with a pin on the swell and the front crank with an arm 31- of a rock-shaft 35, which is journaled on the longitudinal piece 2 and has a leg-piece 36, whereby the swell is operated in the usual manner. The leg-piece may be folded round to the left, so as to come inside of the outside piece 12, and when so folded may be raised, the part 35 sliding in the journal, so as to pass in between the outside board and the bellows.

A spring 37 is provided in each end of the wind-chest for holding it normally extended and springs 37% are arranged to hold the feedbellows normally closed.

The legs 38 are hinged to the bottom of the frame, so as to fold in, as shown in Figs. 2 and S. Stirrup-straps 39 are attached to the bottom of the bellows and provided with stirrups 40 for operating the bellows. These straps are adapted to fold over the legs and their detachable brace a1 when folded and placed on the bottom of the instrument, as shown in Fig. 3. The bottom is provided with eccentric buttons 42 for holding the stirrups in place when folded, as seen in Fig. 3. The rear is provided with a wire brace 43, which is pivoted at the rear end, so that the front may be raised to support the lid 44 in the position shown in Fig. 1.

The under side of the lid is provided with a wire spring 45, which is adapted to hold the music-book in place before the player, as illustrated in Fig. 1.

Detached pedals 46 may be used with the stirrnps, if desired.

The instrument thus constructed is strong and durable and at the same time light and convenient to be carried about. It can easily be carried by means of an ordinary shawlstrap when folded, and also can be stored in small space.

Having thus described my invention, what I claim, and'desi-re to secure by Letters Patent, 1s-

1. In a portable organ, the box consisting of a frame having grooved corner-posts connected by side and end pieces and middle and bottom boards, as shown, and veneer boards in the grooves of the corner-posts to form the exterior of the box, the folding legs hinged to the bottom of the frame, the flexible straps attached to the bottom of the bellows and provided with stirrups, and eccentric buttons attached to the bottom of the box for securing the stirrups, straps, and legs when folded, substantially as specified.

2. In a portable organ in the class shown and described, and in combination, the swell 31, the crank 33, and rock-shaft 35, provided with the arm 34, and the leg-piece 36, said rock-shaft being so attached as to permit the leg-piece to be raised inside of the casing, substantially as specified.

3. In a portable organ of the class shown and described, and in combination, the pivoted brace 43, the lid 44, and the spring 45, all arranged to operate substantially as specified.

- PETER BILHORN.
